We highly recommend that you don’t move forward until or unless you’ve made a proper backup of your device.

Updating Over-The-Air (OTA)

Considering you have at least 2.5GB of space free on your iOS device, fully charged and connected to the Internet via WiFi, follow the steps outlined below.

1. Launch the Settings app from your home screen.

2. Now tap on ‘General.’

3. Look for an entry labelled ‘Software Update’ and tap on that as well.

4. Your iPhone, iPad or iPod touch will look for the update and present it to you. Go ahead with the installation process by tapping on ‘Download and Install.’

This can take a while depending on the amount of content you already have on your device. And also, since you’re updating from iOS 8.x to iOS 9 via OTA, hence you won’t lose your files.

Install Fresh / Clean Using iTunes

1. Download and install the latest version of iTunes on your PC or Mac. Don’t have iTunes installed? Then you can grab it from here: apple.com/itunes.

5. Hold down the left ‘Option’ key if you’re on a Mac, or the left ‘Shift’ key if you’re on Windows, then click on the ‘Restore iPhone’ button.

6. A new pop-up window will appear asking you to point it towards an IPSW file. Select the iOS 9 firmware file you downloaded in step 2.

7. iTunes will now extract the firmware file and restore it onto your device.

This process can take a while, but in the end, you’ll be presented with a fresh sight of iOS 9 on your iPhone, iPad or iPod touch.

Update Using iTunes

Although the above two mentioned procedures are the best to take if you’re looking to update your device, but if you want to take the good old fashioned route, then you can update your iOS device directly using iTunes without going into much hassle.

1. Download and install the latest version of iTunes onto your PC or Mac.

2. Connect your iOS device to your computer using a USB cable.

3. Select your iOS device in iTunes from the top left hand corner.

4. Now click on the ‘Check for Update’ button, which can be found right next to the ‘Restore iPhone’ button.

If there’s an update present, iTunes will notify you of it. Simply go ahead with the installation process and iTunes will even download the IPSW file for you so you don’t have to do much legwork from your end.
